Brake System
The machine is provided with a dual circuit, all hydraulic, brake
system with one circuit for each axle. Each circuit meets the
requirements for secondary brake capability.
Parking Brake
The parking brake is a wet disk brake built into the front axle.
The brake is applied by spring force and is released
hydraulically.
Steering System
The machine uses a load sensing, hydrodynamic steering
system. It has a steering arc of 40°.
Cabin
The cabin has a heating and ventilation system with defrosting
for front and rear windows. Air-conditioning is standard. The
cabin has two emergency exits, the door and right side window.
FOPS and ROPS
The cabin is approved as a protective cabin according to FOPS
and ROPS standards. FOPS is an abbreviation of Falling Object
Protective Structure (roof protection) and ROPS is an
abbreviation of Roll Over Protective Structure (roll over
protection).
Never carry out any unauthorized alterations to the cabin, e.g.
lowering the roof height, drilling, welding on brackets for fire
extinguisher, radio aerial or other equipment, without first having
discussed the alteration with personnel at the DOOSAN
Infracore Engineering Department. This department will decide
whether the alteration may cause the approval to become void.
It is important that all parties concerned are aware of these
regulations.
Hydraulic System
The hydraulic system use a gear pump. The first pumping
section supplies oil for the front attachment. The second
pumping section supplies oil for the steering cylinders. Surplus
oil which is not necessary for the steering function is directed
into control valve to join the first pump is oil by the priority valve.
Pilot pump oil is used for brake and pilot line operation.
